Correction, the numeral are Indian numerals, they were just introduced to the west by Arabs from India, they were discovered by Indians in the first place.

Today I learned that Leonardo Fibonacci just used the rabbit illustration as an example problem to answer in his book that was about introducing arabic arithmetic to italian merchants. Not as a pattern in nature. Like at the end of a math chapter it has little problems that, if you can answer, you've got the gist of the chapter. Also, fibonacci wasn't his name... it was given to him by a historian guillaume libri in 1838 and that wasn't even the name he gave him. Filius Bonnaci was the name which means son of bonnaci. All my life i've been lied to!

The Fibonacci sequence isn't mathematics. It's simply a natural phenomenon that can be described mathematically.

Author Russell Delbridge ( ago)
Did you really just say math was invented by nature? Do you understand the depth and breadth of that statement? I think its more obvious to say the Universe was created with math....don't you?

Author 2consider ( ago)
Nature cannot make anything!
To make something requires intelligence. So unless nature is a thinking and reasoning being, then nature did not make mathematics or the sequence.

However, if the sequence was made, it was made by a thinking and reasoning being, we might call it God.

Author Sanjit Suresh (1082 years ago)
When you said that you get the same number when dividing almost all two successive Fibonacci numbers (1.55), I was a bit confused because I always thought that you never get the same number as the ratio- it approaches the golden ratio as the numbers in the Fibonacci sequence get infinitely large? I think I get what you mean because they become very similar when the Fibonacci numbers you use get very big, but their not the same, right?

Author Ralitsa Kost. ( ago)
probably first and probably last time commenting on Youtube :) :
After years of watching CrashCourse i decided to watch this math video and i see this guy and think "lol is this john green? looks like him but i feel its not" so i check out the comments to find out the name of this guy cause i've seen him in CrashCourse but i just blanked and couldn't come to terms with it. found out its hank green. searched him. found out his brother is john green. my world is complete. Life makes sense. (no wonder he looks the same but different in crash course videos.)

what i learned the most from this video : hank and john are brothers and more than 1 green exists and hank lives in montana and the Fibonacci sequence was made 1300 years ago in India.

I hope that one day you too can solve life and feel wholeheartedly complete with a simple math video - 3 min 19 sec of your life.

Interesting to see that everything is arranged. Everything has its own sequence and fits. From flower petals to the shape of our milkkyway to the shape of things in the rest of the universe, its ALL in the sequence. Yet they still claim it was an explosion of nothing because nothing happened to it. _suure_

ha! the Fibonacci sequence is my favorite of all sequences! I learned it when I was seven. I love it it is so amazing and if you think about it our odd to even with some skip counting in it is the also the Fibonacci sequence too! I LOVE the... 1 2 4 8 16....but just in a spiral!

'Math was invented by a little something called Nature' said this man.
"Nature" an unintelligent nonliving imagined mother nature... that does not do anything, doesn't manage anything, but Nature follows the established laws, governed often by electromagnetic forces, but other fundamental forces as well in nature.

The infinitely intelligent being created things like this to point us to him... but we choose our response. This is His goal, to reveal what is in our hearts.

Romans 1:19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.

21 For although they knew God,
they neither honored him as God
nor gave thanks to him...

"Math was invented by Nature" – Math is a human construct, so not sure if that is really correct.

Which leads to the question: did humans discover or invent math??

I think this is the only scishow episode EVER i didn't learn a thing. That's not because the video was bad; I just had to write a 20 page paper on this all and read about a hundred pages getting my source info. (I am meaning to complement Hank; he is brilliant, just like his brother.)

Fantastic video! Told me exactly what I wanted to know. By the by, is the presenter okay? He put the information across clear as crystal (I got it and I'm definitely on the slow side!) but I'd be cautious about leaving him alone in a room with a knife and a toaster. Thanks for the info anyways, I'll be sure to check out some of your other videos some time!

1,1,2,3,5,8,13,21,34,55,89,144... (...233.377.610...)
- I was noticing a while back that 144 is the 12th # in the sequence...
- 12 is also its root
- &if you take144's mirror-441, it's root is 21, the mirror of 12 who's square is 144
- same thing with 13 (13x13=169 31x31=961)
( I haven't bothered to check how many more numbers might do that but I notice that not all do, so that' is kind of interesting but I don't know if its profound or significant) or if I should see it as pointing toward something else.

Also, this could be meaningless or just coincidence... but I was also recalling how I read that the Mayan's use 144,000 (144,000 days in a Baktun) and also 144,000 is used in the Christian Bible too. Maybe someone has some thoughts on this too.

Also, the divine number is neat in the way in which if you square 1.618 it will be roughly the same as if you added 1.0 to it. Kind of weird.

Leonardo Fibonacci the Catholic mathematician.

Nature: from the Egyptian word NETER - which meant "of God; Spirit".

NETER literally meant God in Egyptian. Thanks to NETER, we can study the Fibonacci sequences.
